An Egyptian man surfing the internet for porn sites collapsed in shock after he discovered his wife of 16 years starring in 11 X-rated movies.

The man, identified only as "Ramadan", was in an internet café in Dakahlia, Egypt, when he made the shock discovery.

Shortly after logging on he discovered that his wife of 16 years and mother of his four children had starred in at least 11 movies. Ramadan was said to have collapsed in shock at the discovery.

"I found 11 films showing my wife in indecent scenes with her lover. It was the first time I watched a porno film and I did it just out of curiosity," he told Emirates247.com. When he came to, he went home to confront his wife, the site said.

She denied his accusations at first but then admitted that she had starred in the films because she was no longer in love with him and he was old.

"She first denied it and accused me of being insane before I faced her with the films. She then confessed to be still in love with her [former] boyfriend, saying he is as young as her and that I am an old man."

Ramadan said he believed he was in a happy marriage until he saw the films.
